The EU Commission is about to debate proposals that would force corporate boards to reserve 40% of their seats for women (click here for the story). Earlier this month, I posted about a new study which found that gender diversity is good for corporate performance. This study implies that it is in a company's interest to have women on boards and that quotas are unnecessary. Nevertheless, quotas are becoming increasingly common in the EU.
The Berkeley Earth Project , an independent study of global warming, has found that the earth has become a degree warmer over the past half century. However, the statistical uncertainty surrounding pre-1920 estimates makes it very hard to say much about long-term trends - click here for graph . This is one of my concerns with the global warming debate - we simply don't have trustworthy long-run data which looks at temperature changes over the last millennium (or two). My second concern with the global warming debate is that it is very hard to prove any sort of casual link between global warming and human activity. The scientists may be able to show correlation between global warming and our production of carbon dioxides etc., but correlation is not causation. My third concern with the debate is that those who are sceptical or agnostic are stereotyped as flat-earthers or intellectually-challenged crackpots. This only stifles debate and the progress of science itself.
